The baseball cap is the quintessential American hat. It is seen not just on the ball field, but in the stands, on the
streets and even at the workplace. Today, as in the past, the baseball cap serves many functions. It shades a player’s eyes from the sun
during the day and from artificial lights at night. It helps players and fans distinguish members of one team from another. A cap’s distinctive coloring and graphics help promote the team and make for an enticing retail product. And how could a club mount a late-inning comeback without displaying an inside-out “rally cap?”

Old Hat

On April 24, 1849, the New York Knickerbockers, baseball’s seminal organization, adopted the first official uniform. The first baseball caps were chip (or straw) hats. A few years later the club switched to a cap
made of merino (a soft, fine wool) that featured the two main characteristics of the modern-day baseball cap: a crown and a bill
(or visor).

A Star Is Borne

Advertisements in the late 1860s featured numerous styles for baseball caps.
One of the most popular styles of the day, made by sporting goods manufacturer
Peck & Snyder, was simply known as “No. 1.” The cap, worn by such top-flight amateur clubs as the Brooklyn Excelsiors, Philadelphia Athletics, New York
Gothams
and New York Mutuals, featured a star pattern atop the crown. Baseball caps of the late 1860s generally ranged in price from $1.25 to $2 each, depending on the grade of
wool, with flannel being less expensive than
merino.

Spalding Pitches Caps

Ten different cap styles were advertised in Spalding’s Base Ball Guide for 1888. Prices for caps of the era ranged from a low of 12 to 15 cents for cheap muslin and flannel caps, to $2
for the highest quality flannel.

The “Parti-Colored Cap” (No. 1) featured vertical stripes on a “pillbox” crown and a striped bill. Best known as the cap worn by the 1886 World Champion St. Louis Browns of the American Association, the style never quite caught on in the major leagues.

The “Chicago Cap” (No. 5) was the same shape as the “Parti-Colored
Cap,” but featured horizontal (rather than vertical) stripes and a solid-colored bill. The style was one of the most popular among big league clubs of the late 1880s, but by the
turn of the century only a few clubs were still donning caps of this type.

The “College Style Cap” (No. 21) was a solid-colored version of the “Parti-Colored” and “Chicago” caps, with a slightly shorter crown.

The “Boston Style Cap,” with its abbreviated bill and the forward-tilting crown, was available both with (No.
13) and without (No. 7) a star atop the hat.

The “Jockey Shape Cap” (No. 11), patterned after the caps worn in the horse-racing circuit, featured a long bill and large round crown. Though not particularly popular at the time, it is the cap most similar to the modern-day baseball cap.

The “Skull Cap” (No. 19) was similar to the “Jockey Shape Cap,” except that the bill was much shorter.

The “Base Ball Hat” (No. 3), first advertised by Spalding in the 1877 Base Ball
Guide, was a derby-style cap that was never adopted by a major league club.

Burkett’s Bill

In 1895, a number of ballplayers, including future Hall of Fame outfielder Jesse Burkett, experimented with baseball caps that had green-tinted, transparent
bills. The idea was to allow the fielder a better range of view while protecting him from the glare of the
sun, but apparently the see-through bills never caught on.

Catch
That Tiger

The first big league club to place an image of its team nickname on its uniform cap was the Detroit Tigers of 1901 and ’02. In those seasons, the front of the Detroit cap was adorned with the likeness of
a running orange tiger.

Stitch Story

In 1903, Spalding introduced the “Philadelphia Style” cap, which featured
an innovative first: the stitched visor. The subtle addition resulted in a longer-lasting cap that better retained its shape.
By the end of the decade, nearly every baseball cap featured the stitched bill.

A Tip of the Cap

Very few clubs have donned baseball caps with two-toned bills. In 1908, the St. Louis Browns introduced a cap with a bill that was white with a thick trim of brown. The style lasted just three seasons. From 1912 through 1915, the Washington Nationals (later known as the Senators) donned caps with a dark blue bill with a thin trim of white.

Pennsylvania “Pillboxes” Produce Plenty of Pennants

By 1905, the “pillbox” baseball cap was rarely seen on big league diamonds, but the style did experience two noteworthy revivals. The Philadelphia Athletics donned a horizontally striped “pill box” cap from 1909 through 1914. The old-fashioned style evidently worked wonders as Connie Mack’s club won four American League pennants and three World Series Championships during the six years the cap was worn. The distinctive caps can be seen on the Hall of Fame plaques of three members of this Athletics dynasty: Frank Baker, Chief Bender, and Eddie Plank. The striped “pillbox” cap also made a
comeback in 1976 when five National League clubs celebrated the “Senior Circuit’s”
100th anniversary by adopting the nostalgic style. While the Reds, Mets, Phillies and Cardinals wore the caps during the centennial season alone, the Pittsburgh Pirates retained the style from 1976 through 1986, including their Championship season of 1979.

No-Go Logo

The last big league club to don a cap without a letter or logo on the front was the 1945 St. Louis Browns, who wore a white cap with thin orange and brown stripes and a solid brown bill.

One-Size-Fits-All

Though today’s big league clubs still use fitted caps, the clubs of the
All-American Girls Professional Baseball League of the 1940s and ’50s used caps
with elastic bands in the back so that they were one-size-fits-all.

Angels Say “Halo”

Just a few months into their inaugural season of 1961, the
American League Los Angeles Angels adopted caps with a silver halo on the crown. The Angels’ halo cap lasted through the 1970
season, after which the design element was removed from the top of the
cap and a small halo was incorporated into the team’s logo.

Captain’s Caps

The short-lived Seattle Pilots of 1969 incorporated an ingenious graphic element on the bill of their caps: two golden braids (sometimes referred to as
“scrambled eggs”) similar to those worn on the hats of
U.S. Navy officers and commercial airline captains. When the club moved to Milwaukee just prior to the 1970 season, the team was renamed and the creative cap design abandoned.

Stars and Stripes

While the Pittsburgh Pirates of 1976-1986 wore the old-fashioned, striped “pill box” cap, their most innovative alteration to the baseball cap was introduced during their championship
season of 1979. In a practice reminiscent of the merit badges doled out by Coach Woody Hayes of the Ohio State Buckeyes football team, Willie Stargell handed out gold “Stargell Stars” to teammates in recognition of various on-field achievements. The stars were then sewn to the honored player’s cap,
either between the horizontal stripes or on the bill. Stargell later introduced
stars with a small letter “S” in the center, but the merit badges
lasted just a few seasons. When Stargell passed away in 2001, the Pirates donned a “Stargell
Star” on the front of their jersey in memory of “Pops.”

Rouge, Blanc et Bleu

Perhaps the most striking baseball cap of modern times was worn by
the Montreal Expos from 1969 to 1991. The six panels that made up the
crown were colored red, white and blue, matching the color scheme of
the club’s logo
